Oscillation extraction device and method for furfural in transformer oil

Abstract

The invention discloses a vibration extraction device and method for furfural in transformer oil. The device comprises a fixing hanging seat, test tubes, a rotating motor and a rotating shaft; whereinthe rotating motor is arranged in the fixing hanging seat; the power output end of the rotating motor is connected with the rotating shaft; the rotating shaft is connected with a test tube rotating mechanism for driving the test tube to rotate, the test tube is connected with the test tube rotating mechanism, a tested sample is filled in the test tube, a test tube sealer for sealing the tested sample is arranged at the opening of the test tube, the included angle between the axis of the test tube and the axis of the rotating shaft is adjustable, and the fixing hanging seat is fixed on a vertical mounting surface during use. According to the invention, oscillation extraction can be carried out on a transformer oil sample more fully, manual oscillation operation is avoided, a large amount of furfural liquid phase extraction time is saved, the labor intensity of an operator is reduced, the oscillation angle can be adjusted, and thereby the experiment efficiency and the test precision areimproved.

Description

Technical field: [0001] The invention relates to the technical field of transformer oil paper insulation aging prediction and evaluation, in particular to a furfural vibration extraction device and extraction method in transformer oil. Background technique: [0002] As an important equipment in the modern power system, the power transformer undertakes important transmission and distribution tasks in the power grid. Its safe and stable operation status plays a very important role in the power system. Serious power transformer accidents will threaten the entire power grid safe operation, while causing huge economic losses. Furfural is a furan compound produced during the aging process of transformer insulating paper. Its physical and chemical properties are stable and it is liquid within the operating temperature range of the transformer. Since furfural is only related to the aging decomposition of cellulose and has nothing to do with transformer oil, the content of furfural i...

Problems solved by technology

However, in the furfural liquid phase extraction technology, the artificial vibration method will consume a lot of time in the extraction process, and the vibration extraction effect is poor and the efficiency is low.

[0005] In summary, the furfural liquid phase extraction technology still has the problem of insufficient vibration, which leads to a laborious extraction process and affects the accuracy of the detection experiment.
